By my reckoning, the glider pilot (having entered serious IMC at around the 2:30 mark) took about 10-15 seconds to lose it totally .... unless you are an experienced I/F pilot with, at the very least, limited panel instruments, VMC into IMC near invariably works out to be a bad outcome. That this pair survived involved nil management and an incredible amount of good luck.
Most of us who are rusty I/F pilots treat it with the same (very) healthy respect (fear ?) ...
(Can't say that I was impressed watching the slip string's gyrations along the way .... seems a lot of folks still view the rudders as footrests.)
